N2 - The sea-sand mining has been carried out in the coast of western part of Japan since the early 1970's. Mined sea-sand is mainly used as fine aggregate of concrete structures. Mining a large amount of sea-sand near the coast induces the possibility of beach erosion and devastation of fishing grounds. In order to evaluate its influence on coastal environment, the present situation of sea-sand mining has been investigated in seven prefectures of Kyushu island in Japan. The sea-sand mining in Kyushu Island is classified into two types. One in the mining in the sea areas where sea-sand reserves are limited. In these areas, the compatibility between the sea-sand mining and the protection of coastal environment will become very important in future. The other is the type that sea-sand has been supplied constantly from rivers or other sea areas. In this case, it will be the most important to keep the balance between the amount of mined sea-sand and that supplied one.
